Touché laat objecten aanrakingen onderscheiden | Core Wetenschappers van Disney Research hebben capacitieve aanraakgevoelige technologie ontwikkeld die allerhande objecten kan laten herkennen welk soort aanraking er plaatsvindt. Ze zien onder andere toepassing in deurknoppen. De onderzoekers van Disney Research en Carnegie Mellon University hebben hun aanraakgevoelige technologie Touché gedoopt. Net als touchscreens in bijvoorbeeld smartphones, maken ze gebruik van capacitieve technologie, waarbij geregistreerd wordt hoe een elektrisch veld van een oppervlak verandert door aanraking met geleidend materiaal, zoals vingers. In tegenstelling tot de huidige toepassingen neemt Touché echter de verandering van meerdere frequenties in plaats van een enkele frequentie waar; een systeem dat ze Swept Frequency Capacitive Sensing noemen. De testapparatuur die het onderzoeksteam gebruikt is klein en relatief eenvoudig. Ook demonstreren ze het gebruik van Touché voor deurknoppen, tafels en handen onderling.
BioDigital Human MaKey MaKey turns anything into a touchpad As I discovered when reviewing the Minty Geek Electronics Lab a while back, experimenting with circuit building can be a great deal of fun. There was one particular project in this kit that made use of the human body to complete a circuit, with a simple lie detector test being the end result. With their Makey Makey open source hardware project, Jay Silver and Eric Rosenbaum have taken such touch interaction to a much more entertaining and inventive degree. Everyday objects like bananas, coins, and even Play-Doh can be transformed into a computer keyboard key or mouse click to control onscreen gaming action, play software-based instruments or type out short messages. View all Based on research at MIT Media Lab's Lifelong Kindergarten and two years in the making, the Makey Makey printed board features six inputs on the front for attaching alligator clips. Makey Makey has gone from first breadboard prototype through two more working units and is now entering its final production stage.
Google Glasses (Project Glass) : The Future of Human Computer Interaction? Google made waves on the Internet last month when it unveiled what it is calling Project Glass. The company released some press shots of what the product, Google Glasses, might eventually look like. Resembling a normal pair of glasses in terms of how the user wears them, Google Glasses does not have any lenses. Instead, it has a small tranparent device just over the right eye which serves as a means of displaying information in an overlay manner. Now that the dust generated by the initial furor last month has settled, we sit down and analyze whether Google Glasses is indeed the future of Human Computer Interaction (HCI) and Augmented Reality or just hype. Project Glass – The YouTube Video On April 4th 2012, a teaser video was also released to give the world an idea of what using the glasses on a daily basis might be like. Of course, none of this is particularly noteworthy on its own. The features shown off in the video include: Project Glass – The Facts Project Glass – My View
A Wearable Computer Turns Any Surface Into A Touchscreen | Co.Design Chris Harrison, a PhD student in Human-Computer Interaction at Carnegie Mellon University, is full of interesting interface ideas. One of his latest projects is called OmniTouch, whose prototype design uses a shoulder-worn, depth-sensing camera/projector to create interactive "touchscreens" on anything from a nearby wall to your own forearm. The technology is amazing: OmniTouch’s screenless interface can distinguish between a touch and a "click" (i.e., a command to do something), auto-detect the size of the interface surface (e.g., it will project a short strip onto your arm, but a large rectangle onto the wall), and even recognize the orientation of the image in 3-D space (if you tilt your screen-hand toward yourself, it will consider it "private"; a more flat orientation will be deemed "public"). Obviously, OmniTouch is a proof-of-concept and Harrison realizes that the physical setup has to be miniaturized and refined to viably offer "Wearable Multitouch Interaction Everywhere."
Poor man's MSOP soldering MSOP stands for Mini Small Outline Package, that means that width of 4 leads is just 2mm, exactly the width of a row in a stripboard... Let see how can we solder that though. On a piece of wood we tape carefully 4 thin wires. We start my taping one wire and then taping again a second one at a distance of 2mm, take as much time as you need, this step is crucial, place on top the MSOP to make sure they have the right separation. If you need to make any adjustments use the blade of a cutter to move the wire. We place the MSOP on top and we tape it, then make the necessary adjustments in the separations of the wires. Time to solder, use flux and apply the iron firmly as with any other SMD Once we have one side done we do the other side, this time it will be easier since the other half is firmly fixed, time to correct the separation of the wires too. Once we remove the tape we check the back of the IC to make sure all looks good and clean. And voila, the breakout board :)
Interactive projector that turns any flat surface into a touch screen wins UK design award Light Touch transforms a projected image into a virtual 10-inch touch screen Image Gallery (8 images) Light Blue Opitcs (LBO) has won the Institution of Engineering and Technology (IET) Innovation Awards 2010 prize for Product Design with its Light Touch interactive projector. View all LBO’s proprietary holographic laser projection technology (HLP) was first reported on by Gizmag in 2009, while still in development. WiFi and Bluetooth connections enable wireless device-to-device communication. The HPL technology was awarded the Product Design Innovation Award for 2010 at the IET Innovation Awards (UK), as the judging panel felt that the product both fulfilled all of the major and most of the minor selection criteria for the award, and also believed it would lead to a wide range of potential applications and products.

Harvard cracks DNA storage, crams 700 terabytes of data into a single gram A bioengineer and geneticist at Harvard’s Wyss Institute have successfully stored 5.5 petabits of data — around 700 terabytes — in a single gram of DNA, smashing the previous DNA data density record by a thousand times. The work, carried out by George Church and Sri Kosuri, basically treats DNA as just another digital storage device. Instead of binary data being encoded as magnetic regions on a hard drive platter, strands of DNA that store 96 bits are synthesized, with each of the bases (TGAC) representing a binary value (T and G = 1, A and C = 0). To read the data stored in DNA, you simply sequence it — just as if you were sequencing the human genome — and convert each of the TGAC bases back into binary. It is only with recent advances in microfluidics and labs-on-a-chip that synthesizing and sequencing DNA has become an everyday task, though. Just think about it for a moment: One gram of DNA can store 700 terabytes of data.
The Untold Story of Magic Leap, the World’s Most Secretive Startup worry about tripping over a tethering cable can seed our unconsciousness with doubt. It might look like it’s there, but it won’t feel there. Following his hunch to exploit human biology, Abovitz set off to make an artificial-reality display in a more symbiont way. The phonelike screens used in the majority of head-mounted displays created a nagging problem: They were placed right next to your eyeballs. If the device is generating the illusion of a blue whale 100 feet away, your eyes should be focused 100 feet away. In trying out Magic Leap’s prototype, I found that it worked amazingly well close up, within arm’s reach, which was not true of many of the other mixed- and virtual-reality systems I used. Magic Leap’s competition is formidable. Abovitz realized that VR is the most advanced technology in the world where humans are still an integral part of the hardware. However Magic Leap works, its advantage is that pixels disappear. Peter Jackson agrees.
German student creates electromagnetic harvester that gathers free electricity from thin air A German student has built an electromagnetic harvester that recharges an AA battery by soaking up ambient, environmental radiation. These harvesters can gather free electricity from just about anything, including overhead power lines, coffee machines, refrigerators, or even the emissions from your WiFi router or smartphone. This might sound a bit like hocus-pocus pseudoscience, but the underlying science is actually surprisingly sound. We are, after all, just talking about wireless power transfer — just like the smartphones that are starting to ship with wireless charging tech, and the accompanying charging pads. Dennis Siegel, of the University of Arts Bremen, does away with the charging pad, but the underlying tech is fundamentally the same. The efficiency of wireless charging, however, strongly depends on the range and orientation of the transmitter, and how well the coil is tuned to the transmitter’s frequency. (See: How wireless charging works.)
